Approximation of the integrated density of states on sofic groups
Christoph Schumacher, Fabian Schwarzenberger
In this paper we study spectral properties of self-adjoint operators on a large class of geometries given via sofic groups. We prove that the associated integrated densities of sta…

Erratum: "The problem of deficiency indices for discrete Schrödinger operators on locally finite graphs"
Sylvain Golenia, Christoph Schumacher
In this note we answer negatively to our conjecture concerning the deficiency indices. More precisely, given any non-negative integer , there is locally finite graph on which th…
